Dear Alice:

CENTRAL FILES
DVIR SECTION
As authorized, Blue Ridge Geological Services, Inc. (Blue Ridge) assisted Thomas Built Buses (TBB)
personnel with the stormwater sampling and reporting event at the subject site. The work was performed
in general accordance with the Stormwater Pollution Prevention Plan (SWPPP) and the NPDES Permit for
the subject facility. This report summarizes the field activities and laboratory data as well as provides our
conclusions and recommendations.
Field Aefivities
On April 23, 2018 Blue Ridge personnel performed a stormwater sampling event at the site during a
measurable storm event. Rainfali data was collected from a nearby weather station. According to the station,
0.66 inches of rainfall was recorded during the storm event.
Blue Ridge personnel observed the stormwater discharge at the two stormwater discharge outfalls (designated
as SWO-1 and SWO-2). Field personnel completed a stormwater discharge outfall (SDO) qualitative
monitoring report form for each of the outfall sampling locations (see attached). A copy of these forms
should be placed in the SWPP Plan or a designated file at the facility. The forms should remain on site and
do not need to be submitted to the NCDEQ.
On April 23, 2018 Slue Ridge personnel collected stormwater samples from outfalls SWO-1 and SWO-2.
The samples were placed into laboratory -prepared containers (some with preservatives), labeled with sample
information, placed into a cooler containing ice, and transported to Pace Analytical Services, Inc. (Pace) in
Huntersville, North Carolina. A completed chain -of -custody form was submitted with the samples. The pH
of the samples was measured in the field using an Oakton pH meter and recorded on the SDO forms. The pH
of the water samples collected from outfalls SWO-1 and SWO-2 was 7.07 and 6.99 standard units,
respectively.

Report of Semi -Annual Storntwater Sampling— First Half 2018
Thomas Built Buses, Fairfield Road Facility. High Point, 'VC
NCDEQ COC 4NCGO30009
Laboralory Results
May 2018
Page 2
The samples were analyzed for total suspended solids (TSS) by Method 2540D, oil and grease HEM total
petroleum hydrocarbons (TPH) by Method 1664, and total metals (copper, lead, and zinc) by Method 200.7.
The TSS detected in samples SWO-1 and SWO-2 was 38.3 and 23.3 milligrams per liter (mg/L),
respectively. Oil and grease and total lead were not detected in the samples. Copper was detected in samples
SWO-I and SWO-2 at concentrations of 0.0174 and 0.0157 mg/L, respectively. Zinc was detected in samples
SWO-1 and SWO-2 at concentrations of 0.134 and 0.148 mg/L, respectively. The results are summarized in
the attached table. The outfall sample results were placed on the NCDEQ Stormwater Discharge Monitoring
Rep6rt (SDMR) farm (see attached). The laboratory report is attached.
Conclusions and Recommendations
Our field inspection did not identify any problems 1 issues at the outfalls. Blue Ridge personnel
compared the analytical results to the benchmark values established in the Permit. As shown in Table 1,
the pH, TSS, oil and grease, and total lead of the samples from Outfalls SWO-1 and SWO-2 did not
exceed the benchmark values. However, the concentrations of total copper and total zinc in the
samples from Outfall SWO-1 and Outfall SWO-2 exceeded the benchmark values.
Since copper and zinc have been detected in the stormwater from outfalls SWO-1 and SWO-2 at
concentrations above the benchmark values during two consecutive monitoring periods, Tier Two
monitoring (i.e., monthly sampling until three consecutive results are below the benchmark values) is
required by the Permit. However, on May 5, 2014 the NCDEQ issued a letter to TBB stating that
they do not have to perform monthly monitoring for copper and zinc exceedances. Therefore,
monthly monitoring is not required for these outfalls.
We recommend that a report (the SDO form signed by company personnel) be submitted to the DWQ
office in Raleigh by June 3, 2018. The next semi-annual inspection (qualitative monitoring and
stormwater sampling and analysis) should be performed at the facility between July 1 and December 31,
2018. We appreciate the opportunity to continue to assist you on this project. Please contact the
undersigned if you have any questions regarding this report or the project.
Sincerely,

Subject: 2015 NPDES permit NCG030000 analysis for two Thomas Built Bus Facilities in
Guilford County:(NCG30009 at 1408 Courtesy Rd and NCG30010 at 715 Fairfield Rd).
Enclosed are the storm water discharge monitoring reports for our Courtesy Rd (general permit
#NCG30009) and Fairfield Rd (general permit #NCG30010) complexes. Please find the first
semi-annual analytical data for 2015 performed on March 19, 2015.
On March 19`I1, the Courtesy Rd facility ( NCG30009) continued to detect total copper and total
zinc above benchmark levels at outfalls SWO-04, SWO-5, SWO-5B, SWO-6 and SWO-7.
Copper and zinc were at elevated levels at C-1. There were no benchmark levels exceeded at the
remaining two outfalls SWO-03 and SWO-08. This site's Tier Two monthly monitoring was
change in the May 5, 2014 NCDENR inspection. to semi-annual monitoring and continue
inspection and BN P improvements as discussed for permit compliance.
The Fairfield facility (NCG30010) was qualitative inspective and stormwater analysis on March
19"' as well. The site exceeded benchmark levels for total Cu and total Zn during the March
semi-annual sampling. These outfalls were below benchmark values for pH, TSS, Oil and Grease
and tPH. Thomas Built Buses reviews the data and site activities to continually improve the best
management practices that affect these benchmarks but has not identified specific root cause. The
site required Tier Two monthly monitoring was change in the May 5, 2014 NCDENR inspection
to semi-annual monitoring and continue inspection and bmp improvements as discussed for
permit compliance.

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TfO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

Dear Sirs;
Subject: Tier III notice and 2014- February and March monthly NPDES permit NCG030000
analysis for two Thomas Built Bus Facilities in Guilford County .
Enclosed are the storm water discharge monitoring reports for our Courtesy Rd (general permit
#NCG30009) and Fairfield Rd (general permit #NCG30010) complexes as required by NPDES
storm water pen -nits. The samples were pulled on February 23, 2014 and March 3; 2014. The
samples were collected in lab prepared and preserved bottles and stored on iced when taken to
R&A labs (NC cert.#34). The samples wvere analyzed for the new metals Cu, Zn, Pb, pH, TPH,
and TSS. The analysis is summarized on two sets of attached forms SI U-245.
On January 17, 2014, Ms. Sandra Carter of DTNA met with DWR officials to discuss storm
water issues and develop a response to mitigate ongoing storm water issues for all North Carolina
Daimler Trucks N.A. manufacturing sites. Daimler remains committed to meeting the intent of
our facility pen -nits and the protecting surface water bodies of this state. NVe look forward to
continuing to work with the DWR in maintaining appropriate standards to reach these goals.
A Tier III response has being prepared and implemented for Zinc and Copper for NCG030010 at
outfalls SD004, SDO05 & SDO06 as indicated by the results for February. In March, Tier III was
triggered for SDO02 for NCG030009. Thomas Buses has been sampling the storm water at
various outfalls at each facility in general accordance with the NPDES permit. Zinc and/or zinc
and copper have been detected in three of the outfalls at concentrations above the benchmark
values in the permit on four occasions at the Courtesy Rd facility (NCG030010) and for zinc at
the Fairfield Rd Facility (NCG030009). Thomas Buses has instituted tier I and tier 2 actions in
the area of these outfalls including monthly monitoring and sampling, inspections, source and
operational controls and physical improvements to reduce the concentrations of these constituents
in the storril water. We are also inspecting and sampling other areas around and up gradient of
these outfalls to determine other possible sources of these metals in the storm water.
Please contact me if you have any question regarding this data or any other item

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."
